Groundwater recharge can cause the ground to rise due to increased water pressure in the soil. To understand this process better, researchers used computer simulations to study how different soil types and initial water levels affect groundwater recharge and ground uplift. They found that a higher initial water level led to more ground uplift, but didn't affect the total amount of water recharged. Additionally, sandy soil allowed for more water to be recharged compared to other soil types, even though it caused less ground uplift.
